Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).
解决办法:
1 运行cmd->netstat -avo,
找出占据了8005, 8080, 8009端口的PID
2 任务管理器
找出该PID的任务,右键->结束任务
3 回到Eclipse,重新Start
